What is abdominal ultrasound?

Abdominal B-ultrasound can be called abdominal ultrasound or abdominal B-ultrasound. The most common ultrasound method, abdominal B-ultrasound, is to place the B-ultrasound probe in the lower abdomen to observe the pelvic cavity, focusing on the uterus, adnexa and pelvic cavity. You need to drink about 1000 ml of water half an hour to one hour before the examination and hold your urine as much as possible. Because only when the bladder is full to a certain extent can the uterus be squeezed from the deep pelvic cavity to the lower abdomen. Through the light and dark contrast of the image, the uterus and ovaries can be clearly observed, so it is best to carry a bottle of water with you to replenish it in time. There will be a little bit of swelling and pain when you are examined after holding your urine.

What is vaginal B-ultrasound?

Vaginal B-ultrasound can also be called vaginal ultrasound, vaginal B-ultrasound, and vaginal ultrasound. It is a type of intracavitary ultrasound, which is a method of ultrasound examination in which the ultrasound probe is placed directly into the vagina. my country began to use transvaginal ultrasound in 1986. Due to its advantages, it has developed rapidly in the past two years, especially in the field of obstetrics and gynecology, and has become one of the indispensable and important means of obstetrics and gynecology examination.

Vaginal B-ultrasound examination can detect gynecological diseases such as uterine fibroids, endometrial cancer, ovarian tumors, and hydrosalpinx.

It is usually used to observe the follicles, endometrium, lower uterine segment, cervical placenta position, etc., and is also used to check whether the abdominal wall is thickened. Abdominal ultrasound is mainly used in the middle and late stages of pregnancy, and is also used for those with large uterine and pelvic tumors to detect the relationship between the uterine appendages and surrounding organs.

2. Vaginal ultrasound can detect pelvic fluid effusion. Vaginal B-ultrasound is an ultrasound method in which the probe is inserted into the vagina to explore the uterus, ovaries, fallopian tubes and pelvic cavity. It is also a type of ultrasound, but the probe reaches a different part. Therefore, compared with abdominal B-ultrasound, it has the advantages of not having to hold urine, high resolution, and less interference from abdominal intestinal gas. Generally, the diagnostic value of vaginal ultrasound is greater than that of abdominal B-ultrasound, but abdominal B-ultrasound will be used only when some tumors are too large to be observed through the vagina. In addition, the power of vaginal ultrasound is slightly greater than that of abdominal ultrasound, so vaginal ultrasound is not recommended within the first three months of pregnancy.
